Sealing Component With Integrated Electronic Filter Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is ensuring that air filter cartridges used in air treatment systems for commercial vehicles are compatible, as standardization of threads does not guarantee matching performance, potentially impairing safety by affecting the operation of critical systems like braking.
Innovation Solution
A sealing component with an integrated electronic component that has a filter-type-specific circuit and memory, allowing the air treatment system's controller to identify and verify the filter type through electrical signals, ensuring only compatible cartridges are used, and incorporating sensors for optimal filter replacement timing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If standardized threads are used for air filter cartridges, then ease of installation and interchangeability are improved, but reliability deteriorates because incompatible filters can be installed that do not meet performance requirements
Solution Approach 1:
An electronic component with memory is introduced as an intermediary between the filter cartridge and the air treatment system controller. This component stores filter type information and is read by the controller to verify compatibility before allowing operation, thus preventing incompatible filters from being used while maintaining ease of installation through standardized threads
Solution Approach 2:
The filter type identification information is pre-stored in the electronic component during filter manufacturing. Before the filter is installed and used, the controller performs a preliminary read operation to verify compatibility, ensuring that only suitable filters are activated in the system
2Reliability
If electronic components are integrated into sealing components, then reliability is improved through filter type verification, but device complexity increases due to additional electronic components and manufacturing steps
Solution Approach 1:
The electronic component is merged with the sealing component by integrating it into the sealing body's cavity. The sealing component serves dual purposes: providing the sealing function and housing the electronic component with its memory and antenna, thereby reducing overall device complexity compared to separate components
Solution Approach 2:
The sealing component is designed to perform multiple functions: mechanical sealing between the filter cartridge and housing, and housing the electronic identification component. This multi-functionality reduces the total number of components needed in the system
3Object-affected harmful factors
If the sealing body completely encloses the electronic component, then protection of the electronic component is improved, but ease of manufacture deteriorates due to complex integration requirements
Solution Approach 1:
The sealing body is designed with a cavity that segments the internal space to accommodate the electronic component. This segmentation allows the electronic component to be placed and protected within the sealing body while maintaining a relatively simple manufacturing process through one-piece molding or assembly
